Abstract

The mass measurement of ²²Mg was performed with the ISOLTRAP Penning trap mass spectrometer at ISOLDE/CERN. It was observed that the measurement on ²¹Na and ²²Mg yield a ²¹Na(p, γ)²²Mg resonance energy into the 5713.9-KeV 2⁺ of E_R=209.7(1.2). A comparative halftime value for the superallowed βdecay of ²²Mg was obtained to further test the conservedvector current hypothesis. The results show ²²Na contevt in ONe nova ejecta does not contradict the upper limits from observational searches.
